Skyscraper Sunflower

Skyscraper Sunflower is an open-pollinated sunflower variety that will reach for the skies with stalks that can get as tall as 14.' These garden giants have strong, sturdy stalks with dark green leaves and blooms from top to bottom. The foliage usually extends 2' from the stalk, so be sure to give each plant plenty of room for maximal growth.

Skyscraper Sunflower produces blooms that can grow as large as 14" in diameter. The petals are bright yellow with a orange to green disk. This variety is heat-tolerant, drought-tolerant and performs well when grown in the hot summer months. Once the plants are done blooming, the jumbo Seeds may be saved for roasting.

Skyscraper Sunflower can be direct-seeded or transplanted. Direct-seeding can be easily done with a walk-behind planter like our Hoss Garden Seeder. We recommend using a #3 seed plate and modifying the hole size to fit the variety being planted. Sunflower seed size can vary greatly from one variety to the next, therefore it's important to always calibrate the seed plate hole size for the variety being planted. Sunflowers grow well when planted on double rows with drip irrigation. Lay one row of drip tape and plant on both sides of the tape to maximize garden space.

Sunflowers also perform well when transplanted. They grow great in our heavy-duty seed starting trays. Transplants are ready to go in the ground when plants can be easily pulled from the seed starting trays. For increased storage potential, harvest sunflowers when blooms are closed. Blooms will then open when cut and placed into a container with water.
